In this video, Mr. Jay explains how to find the interquartile range (IQR) using box plots. He introduces the concept of IQR, which represents the spread of the middle 50% of data. The video demonstrates how to calculate the IQR by subtracting the first quartile from the third quartile, using a student's math test scores as an example. The IQR is calculated to be 6, indicating the range of the middle 50% of scores. The video concludes with a brief mention of additional resources for learning more about box plots.
